Unfortunately, I didn't find the option to attach a file in PM or e-mail from the forums page, so I write here. I guess only some sort of characters reproduce the bug... The folder or the file alone don't trigger the bug, but both of them do. Just cd somewhere, unpack there 'test' directory and type: ls test/<TAB><TAB> In my case the command disappears, but it still offers the list of files in 'test' on each <TAB> keypress if I don't press anything else.
